Observation geometry for uncertainty-aware Hamiltonian inference and experimental design in quantum magnets
Roy Liu, Venugopal Ranganathan, David Dahlbom +12
Determining microscopic interactions from spectroscopic and scattering measurements is central to understanding quantum materials, yet it often remains unclear which interactions c…
Frustration induced dimensional reduction and coexistence of long and short-range magnetic order in NdCl
Eli Zoghlin, Matthew B. Stone, Vasile O. Garlea +3
The phenomenon of frustration greatly enriches the accessible physics of quantum magnets. With this in mind we study the magnetism of NdCl using a combination of bulk propert…
Codimension-Two Spiral Spin-Liquid in the Effective Honeycomb-Lattice Compound CsFeCl
Shang Gao, Chris Pasco, Otkur Omar +7
A codimension-two spiral spin-liquid is a correlated paramagnetic state with one-dimensional ground state degeneracy hosted within a three-dimensional lattice. Here, via neutron sc…
Dichotomy of flat bands in the van der Waals ferromagnet FeGeTe
Han Wu, Jianwei Huang, Chaowei Hu +28
Quantum materials with bands of narrow bandwidth near the Fermi level represent a promising platform for exploring a diverse range of fascinating physical phenomena, as the high de…
From weakly interacting spinons to tightly bound triplons in the frustrated quantum spin-Peierls chain
Pyeongjae Park, Bo Xiao, Karolina Górnicka +7
Fractionalized quasiparticles and their confinement into emergent bound states lie at the heart of modern quantum magnetism. While the evolution into magnonic bound states has been…
Crystal field splittings and magnetic ground state of the square-lattice antiferromagnets YbBi2ClO4 and YbBi2IO4 with Jeff = 1/2
Pyeongjae Park, Qianli Ma, G. Sala +5
We report on the crystal field level splitting and magnetic ground state of the Jeff = 1/2 square lattice antiferromagnets YbBi2ClO4 and YbBi2IO4 using powder inelastic neutron sca…
